Dual-Blower Railcar Unload System

The vacuum-pressure rail unload system unloads powder, pellet, and granular material from railcars at conveying rates in excess of 100,000 lb/hr. Using separate vacuum and pressure blowers, the system unloads material from the railcar at higher conveying rates and for longer conveying distances. A vacuum blower draws material from the railcar to a self-cleaning filter receiver that separates the product from the conveying air. Mounted below the receiver is an Aerolock rotary valve that meters the product into the pressure side of the system for final delivery to storage. Dual-blower systems are available in 3- to 10-in. line sizes and include a control panel, properly-sized blowers, railcar adapter kit, and hoses.
